It's been a rough week for Tony Stewart, and it wasn't getting much better Friday for the reigning NASCAR Sprint Cup Series champion.
Stewart also is co-owner of his Stewart-Haas Racing team, and earlier this week Office Depot said it was dropping its primary sponsorship of Stewart's No. 14 Chevrolet after this season.
"It is a big void," Stewart told reporters at Richmond (Va.) International Raceway, site of Saturday night's Cup race, according to a transcript provided by Chevrolet.
"It's part of a bad economy," he said. "Been listening to all the politicians speak about how they are going to make things different. I haven't seen anything get any better yet.
